Definitions

  • the present invention relates to the inhibition of exoprotein in an absorbent article, such as vaginal tampons and sanitary napkins. More particularly, the invention relates to the incorporation of amide compounds, either alone, or in combination with one or more ether compounds and/or amine compounds into such absorbent articles and these compounds effects on Gram positive bacteria.
  • Disposable absorbent devices for the absorption of human exudates are widely used. These disposable devices typically have a compressed mass of absorbent formed into the desired shape, which is typically dictated by the intended consumer use. In the area of a menstrual tampon, the device is intended to be inserted in a body cavity for absorption of the body fluids generally discharged during a woman's menstrual period.
  • vaginal exudate The bacterial flora of the vagina is comprised of both aerobic and anaerobic bacteria.
  • the more commonly isolated bacteria are Lactobacillus species, corynebacteria, Gardnerella vaginalis , Staphylococcus species, Peptococcus species, aerobic and anaerobic Streptococcal species, and Bacteroides species.
  • yeast Candida albicans
  • protozoa Trichomonas vaginalis
  • mycoplasma Mycoplasma hominis
  • chlamydia Chlamydia trachomatis
  • viruses Herpes simplex .
  • Physiological, social and idiosyncratic factors affect the quantity and species of bacteria present in the vagina.
  • Physiological factors include age, days of the menstrual cycle, and pregnancy.
  • vaginal flora present in the vagina throughout the menstrual cycle can include lactobacilli, corynebacterium, ureaplasma, and mycoplasma.
  • Social and idiosyncratic factors include method of birth control, sexual practices, systemic disease (e.g. diabetes), and medication.
  • Bacterial proteins and metabolic products produced in the vagina can affect other microorganisms and the human host.
  • the vagina between menstrual periods is mildly acidic having a pH ranging from about 3.8 to about 4.5. This pH range is generally considered the most favorable condition for the maintenance of normal flora.
  • the vagina normally harbors the numerous species of microorganisms in a balanced ecology, playing a beneficial role in providing protection and resistance to infection and makes the vagina inhospitable to some species of bacteria such as Staphylococcus aureus ( S. aureus).
  • S. aureus Staphylococcus aureus
  • the low pH is a consequence of the growth of lactobacilli and their production of acidic products.
  • Microorganisms in the vagina can also produce antimicrobial compounds such as hydrogen peroxide and bactericides directed at other bacterial species.
  • antimicrobial compounds such as hydrogen peroxide and bactericides directed at other bacterial species.
  • One example is the lactocins, bacteriocin-like products of lactobacilli directed against other species of lactobacilli.
  • S. aureus can produce and excrete into its environment a variety of exoproteins including enterotoxins, Toxic Shock Syndrome Toxin-1 (TSST-1), and enzymes such as proteases and lipase.
  • TSST-1 Toxic Shock Syndrome Toxin-1
  • enzymes such as proteases and lipase.
  • S. aureus is found in the vagina of approximately 16% of healthy women of menstrual age. Approximately 25% of the S. aureus isolated from the vagina are capable of producing TSST-1. TSST-1 and some of the staphylococcal enterotoxins have been identified as causing Toxic Shock Syndrome (TSS) in humans.
  • TSS Toxic Shock Syndrome
  • TSS Symptoms of TSS generally include fever, diarrhea, vomiting and a rash followed by a rapid drop in blood pressure.
  • Systemic vital organ failure occurs in approximately 6% of those who contact the disease.
  • S. aureus does not initiate TSS as a result of the invasion of the microorganism into the vaginal cavity. Instead as S. aureus grows and multiplies, it can produce Toxic Shock Syndrome Toxin 1 (TSST-1; synonyms: pyrogenic exotoxin C and enterotoxin F). Only after entering the bloodstream does the TSST-1 toxin act systemically and produce the symptoms attributed to Toxic Shock Syndrome.
  • Menstrual fluid has a pH of approximately 7.3.
  • the pH of the vagina moves toward neutral and can become slightly alkaline. This change permits microorganisms whose growth is inhibited by an acidic environment the opportunity to proliferate. For example, S. aureus is more frequently isolated from vaginal swabs during menstruation than from swabs collected between menstrual periods.
  • Glyceryl triacetate is readily broken down into glycerol and acetic acid by the enzymatic action of esterase.
  • Esterase is present in the vaginal epithelium and in menstrual fluid.
  • the enzymatic action of the esterase is in tum controlled by the pH of the environment, being more active when the pH is on the alkaline side. Since the pH of the vagina moves toward the alkaline side during menstruation, the enzymatic activity of the esterase automatically increases and attacks the glyceryl triacetate. This releases acetic acid rapidly, which has the potential to reduce the pH and enzymatic activity of the esterase.
  • menstrual fluid is well buffered and the acetic acid is ineffective at lowering the pH of the menstrual fluid.
  • EP-A-483 812 relates to absorbent products such as tampons, sanitary napkins, wound dressings, nasal packing and the like which are adapted to absorb body fluids.
  • active compounds are added which, when exposed to bacteria in absorbent products, will reduce the amount of toxins produced by bacteria coming into contact with them.
  • These active compounds are selected from among monoesters or diesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms, wherein said monoester or said diester has at least one hydroxyl group associated with its aliphatic alcohol residue, or mixtures thereof, in an amount which is effective to inhibit the production of Enterotoxin A, Enteroxin B or Enteroxin C by Staphylococcus aureus bacteria.
  • ester compounds may have to be added to the absorbent article, such as a tampon pledget, in sufficiently high concentrations to detrimentally effect the normal flora present in the vaginal area.
  • the absorbent article such as a tampon pledget
  • overgrowth by pathogen(s) may take place resulting in a condition known as vaginitis.

Russell-Jones and E. C. Gotschlich, Analytical Biochemistry , 136:175-179, 1984.
  • Enterotoxin B was separated from other proteins in the test samples by sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) electrophoresis.
  • the upper stacking gel used 3% acrylamide gel, the lower separating gel contained 14% acrylamide gel.
  • the upper gel was prepared with a comb containing twenty lanes spanning 15.5 centimeters of the top of the stacking gel.
  • the loading buffer contained 30% [vol/vol] glycerol, 15% [vol/vol] mercaptoethanol, 7% [wt/vol] sodium dodecyl sulfate, 0.0036% [wt/vol] bromphenol blue, and 0.76% [wt/vol] Trizma base with a pH of 6.8.
  • the mixtures were boiled for 5 minutes, then twenty-five (25) microliters of each mixture was placed in a lane.
  • the SDS-PAGE gel was electrophoresed (60 to 80 volts) for 90 minutes or until the dye front was through the stacking gel and for an additional 2.5 hours (160-170 volts) with an electrophoresis buffer of 0.61% [wt/vol] Tris base, 2.85% [wt/vol] glycine, 0.1% [wt/vol] SDS, pH 7.85. Proteins were transferred to a nitrocellulose transfer membrane, available from Schleicher and Schull, Inc., Keene, N.H. 03431, #BA 85, overnight approximately 15 hours at 200 milliamps in a Bio-Rad Trans-Blot® cell. The transfer buffer was composed of 0.3% [wt/vol] Tris base, 1.4% [wt/vol] glycine, 20% [vol/vol] methanol, pH 7.6.
  • the nitrocellulose membrane was treated for 45 minutes at 37°C with 3% [wt/vol] gelatin in 0.02 molar Tris buffer, 0.5 molar NaCI, at pH 7.5 (TBS) to block non-specific reactions, then washed at 37°C with TBS-0.05% [vol/vol] Tween 20 (TBS-Tween) for 45 minutes.
  • TBS-Tween TBS-0.05% [vol/vol] Tween 20
  • the membrane was washed two times in TBS-Tween, then submerged a second time for 1.5 hours at 37°C in a 50 ml solution of TBS-Tween with 25 microliters of goat anti-rabbit IgG conjugated to alkaline phosphatase.
  • the membrane was washed twice in TBS-Tween and twice in TBS.
  • the blot was developed with a reaction solution consisting of 2 mg 5-bromo-4-chloroindolyl phosphatase, 100 microliters of N,N dimethyl formamide, 18 ml 0.15 molar barbitol buffer, pH 9.2, 2 mg nitroblue tetrazolium, and 40 microliters of a 2 molar solution of MgCl 2 ⁇ 6H 2 O, all available from Sigma.
  • the reaction was stopped with a cold water wash.
  • the amount of SEB produced in the presence of the test compound was estimated by a comparison with the staining intensity produced by a serial dilution of SEB.
  • the data in Table VI show that S. aureus HOCH, when compared to the control, produced significantly less SEB in the presence of the amide compounds.
  • the concentration of the amide compound can be adjusted so that there was little reduction in the number of S. aureus cells.
  • the amide compounds reduced the amount of exotoxin production below the detectable range of 0.16 milligrams/milliliter.
  • Another aspect of the invention is for a method of inhibiting the production of exoprotein from Gram positive bacteria in an absorbent product.
  • the method includes the steps of contacting the absorbent article, such as a tampon, with one or more of the above described inhibitory compositions then placing the absorbent article for use so that the production of exoprotein from Gram positive bacteria is inhibited.
  • the absorbent article can have one or more of the inhibitory compositions absorbed into or coated onto the fibers or cover material. Desirably, the production of TSST-1 and Enterotoxin B are inhibited.
